Jewel accidentally added an eleventh drop of food colouring to the last yellow test tube, so she went back and added an extra drop of food colouring to the blue and red test tubes, to keep the experiment &#8216;fair&#8217;. Jewel and I have been talking a lot about the importance of making science experiments &#8216;fair&#8217; by keeping most aspects consistent so we can focus on the effects of just one variable, and this was the first time that we&#8217;d had the opportunity to explore this theory in practice.<\/p>\n<p>Of course, three year old Bumble Bee didn&#8217;t want to be left out of all this food colouring floral fun. I didn&#8217;t want to let her participate in (aka ruin) Jewel&#8217;s experiment, as I knew Bumble Bee wouldn&#8217;t have the fine motor or self control to measure out drops of food colouring one by one, so instead I filled a random glass jar with water, and let her squirt a healthy dose of green food colouring into it, as her own little side project.<\/p>\n<p>We trimmed all the flowers by the same amount (about an inch), and added them to Jewel&#8217;s test tubes and Bumble Bee&#8217;s glass jar. And waited&#8230;..<\/p>\n<div class=\"info-box\">\n<h3 class=\"fun-fact\">Fun Science Facts<\/h3>\n<p>Flowers absorb water through the xylem, which is a tissue of thin tubes found inside the stem. Water is transported up the xylem to the various parts of the plant, including the flower. Various factors help water to move up the xylem, including molecules in the xylem that attract the water molecules, solar energy and transpiration. Transpiration occurs when sunlight evaporates water from flowers, leaves and stems. This loss of water creates a vacuum at the top of the xylem tubes, which encourages water to be sucked upwards to fill the empty space (not dissimilar to the movement of water up through a straw when someone is taking a sip.)
